Chicago's original "city within a city" development is just one more step away from being officially designated a Chicago Landmark by the Chicago City Council. Yesterday, the Commission on Chicago Landmarks unanimously voted to recommend Chicago Landmark status to the Marina City complex. According to Loop North News, the vote took less than three and a half minutes. A resolution will be drafted and will head to the Chicago City Council in December for a final vote. The iconic corncob-shaped twin towers that line the Chicago River have long been an anchor of the Chicago skyline and a favorite for architectural tours and photographers.
